so something is wrong in software, schematics make sense.

bq27200 chip is near blamed isp1707 usb transceiver chip
It's 0x55, because 0xAB and 0xAA contain the write/read bit, which Linux does not consider a part of the address. The read/write functions in code add the write/read bit so that what goes out on wire is an 8 bit 0xAA or 0xAB.

Both - I used the 2 codes first to test it out, then changed /etc/pmconfig to make the change persist across reboots.

oh, so if i change the values, the power saving will be consistent and active even after reboots???

and is this done in xterm? cant cd to /etc/pmconfig, or im doing it the wrong way?

If you edit the /etc/pmconfig file then the changes will persist across reboots, yes - you'll need to be root to do this though. The following should do it (if you've got rootsh installed) - make sure you type it in exactly though!:
Code:
sudo gainroot
echo "sr_vdd1_autocomp 1" >> /etc/pmconfig
echo "sr_vdd2_autocomp 1" >> /etc/pmconfig
Alternately, use vi, vim, mc, or leafpad as root to edit the file.

thanks very much! you save my life again.

when i performed the codes and hit enter, i just came back at /home/user #,

does this mean it was successful or nothing happened???

EDIT: oh, then i reboot the device (in root, typed "reboot")

Yes, it doesn't output anything - you can do "cat /etc/pmconfig" to check that the file has been edited properly (you should see the sr_vdd.... lines at the bottom). After rebooting you can check that the changes are in place by running (you should get "1" back from each):
Code:
cat /sys/power/sr_vdd1_autocomp
cat /sys/power/sr_vdd2_autocomp

yup! thanks!!!! i ran those cat codes and they give me a 1 after hitting enter, and i see sr_vdd1_autocomp 1 and vdd2_autocomp 1 at the bottom after punching the cat /etc/pmconfig.

i also noticed from doing this, my ram usage goes down bout 5-10mb

UPDATE: yey!! so far not experiencing any reboots or issues!

yea i changed those settings in January, added to my batt life significantly, with no ill effects on performance, i dont know why it was disabled out of the box. hmm ... but regardless of that fact it worked.

how did your battgraph have the CPU statistics as well, was it in testing/devel? i only DL'd the version that was in the official maemo repo.
